Abstract

Disclosed are block copolyetheramides suitable for injection moulding, comprising polyamide and polyalkylene ether blocks and having a melting point of from 215 to 223 DEG C, an apparent viscosity, at 230 DEG C, of from 50 to 150 Pa.s, a number average molecular weight of from about 4300 to 50000 and a degree of yellowing, measured by means of an Elrepho apparatus, of not higher than 20. The process for producing said copolyetheramides comprises the polymerization of the polyamide-forming monomer(s) in the presence of hypophosphorous acid and/or meta-hypophosphorous acid and the subsequent polycondensation of the polyamide with a polyalkylene ether having terminal hydroxy and/or amine groups in the absence of polycondensation catalysts.
